TRAIVEPER ATTACHMENT FOR COTTON-PRESSES.

SPECIFICATION forming part of Letters Patent No. 399,441, dated March12, 1889.

Application filed July 12, 1888. Serial No. 279,767 (.No model-'lraniper Alii'tlClllllOllt for (lotton-lresses, of which the followingis a full. clear, and exact 1 description.

Myinvcntion relates to an improvement in trampw attach ments forC()l'l.Oll1 1l(?S-SOS, and 1 has for its objectto provide a tramper ofsimple, durable, and economitml construction, 5 which may be readilyapplied to any press, 1 and which is designed to be o erated by steam.

The invention consists in the novel 0011-, struction and combinat ionofthe several parts, as will be hereinafter fully set forth, and pointedout in the claims.

Reference is to be had to the :weompanying drawings, forming a part ofthis specification, in. which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a front elevz'it ion of a press hav ing my improvementapplied. Fig. 2 is a per spective detail view of the plunger block orhead. Fig. I is a side elevation of the press. Fig.1 is a perspectiveview of the driving mechanism, and Fig. is a longitudinal ver- 1 ticalsection through the plunger block or; head.

In carrying out. the invention four stand 1 ards, 10, are projectedupward from the base of the press, between which standards suitabledoors, 11, are hinged, as best shown in Figs. 1 and 3, and the saidstandards are provided at the upper extremity of each with side bars,12, which bars are usually projected horizontally beyond the front ofthe said standards, as best illustrated in Fig. The 1 respective sidebars are connected at the front and rear above the standards byhorizontal beams 13. The plunger-box or slide 14c is attached to theinner face of the side bars, 12, t and consists, preferably, of fourperpendicular l angled bars, 15, attached one at each corner of theframe formed by the union of the side bars, 12, to the front and rearcross-bars, 13. The said perpendicular angled bars are preferably unitedat. the top by horizontal side and end strips, 16. The plunger 17,adapted to slide in the plungenbox 14:, consists, usually, of fouruprights, 18, united attheir upper ends in any approved manner andhaving attached omitted for that purpose.

to their lower extremities a plunger blocker head, 19, as bestillustrated in Fig. The several uprights 1S constitute the frame of theplunger, and are connected. to the block or head 10 at one end, the saidblock or head being preferably rectangular, an d. one of said uprightsis adapted to slide in each of the angled bars, as illustrated in 1 and3. The plunger further consists of two spaced central uprights, 90, alsoattached to the plunger block or head, being preferably secured theretoby angled plates 21, as best shown in Fig. 2, the rack hereinafterdescribed being 1 do not, however, confine myself to the above mode ofconnection, as other approved or suitable means may be employed.

The upper ends of the central plunger-up rights, 90, extend upward, 1)1'efcrabl v to an equal height with the said uprights 1S, and areprovided upon their outer face with a rack, 22, as shown in Fig. 1. Theplunger block or head 19 is lll'PfOlftl'll) (ODSllfllPliOd with an upper horizontal bmly-btmrd, 23, attached to side and end boards, 24 and25, and to inwardlyextending marginal bottom boards, Ethas best shown inFigs. 2 and 5, in which it will be ob served that a central rectangularopeningflT, is provided in the head.

The purpose of this form of plunger block or head is to prevent thecotton fibers, when compressed, from riding up at the sides of thepress, the tendency being, when the block is carried downward, to drawthe fibers inward.

\Vhile I have described the plunger block or head as constructed ofwood, I desire it to be distinctly understood that I do not confinemyself to any particular material, as the block or head may be, forinstance, constructed of metal.

Upon the upper surface of the rear and front cross-bars, 13, bearingsare secured, in which short: shafts 2S and 29 are respectivelyjournaled, which shafts extend from one outer side bar to a pointopposite the central uprights, 20, of the plunger. Upon the inner t endof each of the said shafts a pinion, S0, is

mounted, which pinion engages, respectively, the rack-surfaces of theplunger-uprights 20,21 5 best illustrated in Fig. 1.

Upon the outer end of each of the shafts 28 and 29 a gear-wheel, 31 and31, is secured, which gears are adapted to mesh one with the other. Uponthe ,front projecting ends of the several side bars, 12, a shaft, 32, isjourualed in suitable bearings, provided at one en d with a pinion, 3S,meshing with the forward gear, 31. At the other end of the said shaft 32friction balance-wheel, 33, is keyed or otherwise secured, provided witha smooth flat outer face, an in wardly-extendin ghub, iii, an d aninwardly-projecting peripheral flange, 35, preferably of a width equalto the width of the hub, as best shown in Figs. 1 and 1-,whereby agroove is formed upon the inner face of the friction balance-wheel forthe reception of the friction-pulley, as will be hereinafter set forth.A second or outer shaft, 36, is also journaled upon the projecting en dsof the side bars, 12, which shaft is provided at one Q and at theoppoend with a drivepulley, or, site end with a friction-pulley, 38, thelatter pulley being adapted to enter the groove on the balancefriction-wheel 33 and alternately engage the inner surface of the wheeland the circumference of the hub. To this end the extremity of the shaft36, carrying the friction-pulley 38, is mounted in a sliding bearing,39,'which bearingis reciprocated through the medium of a lever, l0,pivoted upon the outer face of one of the side bars, 12, the upper endof which lever is united by a connecting-rod, 41, with the slidingbearing 39, as best shown in Figs. 1 and 4. Thus by maflangc of the hubof the balance frictionwheel 33, thereby causing the drive-shaft to bedriven in opposite directions, which shaft in turn cominunicatesmovementto the gears 31 and 31, and the said gears rotating the shafts 28 and 29cause the pinions 30 attached thereto to elevate or depress the plunger.

A brakelever, i2, is pivoted to a standard,

43, which standard is secured. to the side bar,

12, carrying the lever 40, and extends vertically upward a sufficientheight to permitthe said lever 4.2, when brought down to a horizontalposition, as illustrated in Fig. 3, to bear upon the periphery of thefriction balance- .wheel 33.

I desire it to be understood that although specific construction hasbeen shown and described other equivalent construction may be usedwithout departing from the spirit of the invention. The object ofproviding the two shafts 2S and 29 and their pinions 30 is to cause theplunger to move evenly and regularly within the box or slide, and theprime object of the brake-lever 42 is to balance the plunger andregulate the descent of the same.

Having th us described my invention, what I claim as new, and desire tosecure by Letters Patent, is
